The T$_{g}$ of polycyanurate in cylindrical nanoporous confinement

The glass transition behavior of materials under nanoconfinement is often different than their behavior in the bulk. A leading explanation is that enhanced mobility at free surfaces or neutral interfaces results in depressions in Tg, whereas attractive interfaces result in increases in Tg. In this work, we examine the Tg of a polycyanurate using differential scanning calorimetry for both material confined in cylindrical nanopores and for freely-standing nanocylinders. Preliminary results using an alumina nanofilter for the confining matrix indicate that the Tg depression for the supported and freely standing nanocylinders are similar. The implications of the results will be discussed.
